Description

TECHNICAL FIELD The present invention relates to a display method in a disc player.

BACKGROUND ART A small digital audio disc with a diameter of about 12 cm, called a compact disc, includes the number of songs recorded on the disc in the lead area, the total absolute time, the playing time of each song, etc. Information is recorded, and when the disc is reproduced, the recorded information in the lead-in area is always read. Then, the read recorded information is appropriately displayed on the display. Further, in the program area of the disc, information such as the music number for each frame and the elapsed time from the reproduction start time for each music is recorded, and these information are sequentially displayed on the display during the reproduction process. It

In the conventional disc player, regarding the display of the read information from the lead-in area and the read information from the program area, either one is selectively displayed by a changeover switch provided in the operation unit. For this reason, a dedicated switch is required, and particularly in the case of a small player such as a vehicle-mounted disc player, the area of the operation panel surface is limited, which is disadvantageous in effectively using the panel surface.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described points, and by omitting a switch for switching the display between read information from the lead-in area and read information from the program area, the operation panel surface is effectively An object of the present invention is to provide a display method in a disc player that can contribute to utilization.

The display method in the disc player according to the present invention displays the read information for a predetermined time after the reading of the recorded information in the lead-in area is finished, and then displays the reproduction status information based on the read information in the program area. It is characterized by that.

The display method in the disc player according to the present invention is further characterized in that, when another mode is designated within the predetermined time, the display status is immediately displayed.

Example Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

First, in FIG. 1, a slot 4 for inserting a disc 3 to be reproduced is provided in a front panel 2 forming a part of a housing 1 so as to extend in the left-right direction in the figure. The disc 3 has, for example, audio information.
It is a so-called compact disc recorded by PCM (Pulse Code Modulation) and has an outer diameter of about 12 cm. The front panel 2 is further arranged with a plurality of operation keys for issuing various operation commands to the disc player, for example, commands such as play start and disc eject, and these keys constitute an operation key group 5. There is.

In FIG. 2, the disk 3 having the slot 4 inserted therein
Is positioned by a positioning means (not shown) at a predetermined position on the tray 6 (hereinafter referred to as a slot position), and is carried on the tray 6 with a part of the disk 3 protruding outside the front panel 2. The tray 6 has a loading motor 7, which is a drive source, and a drive force transmission mechanism 8 that transmits the rotational drive force of the motor 7 to the tray 6 as a linear drive force in the horizontal and vertical directions in the drawing. It constitutes a loading mechanism for carrying between the position and a reproduction position in the housing 1 which will be described later.

In such a loading mechanism, the tray 6 carries the disc 3 set in the slot position and moves to the right from the solid line position at the time, and the center hole of the disc 3 is fixed to the rotary shaft of the spindle motor 9 in the turntable 10. When it reaches the upper position, it descends directly below, the disc 3 is placed on the turntable 10 and then further descends, and it stops in a state slightly separated from the disc surface as shown by the chain double-dashed line in the figure. By this operation, the loading operation of the disk 3 is performed. The position where the disc 3 is placed on the turntable 10 is the above-mentioned reproduction position. Also, disk 3
The ejecting operation is carried out by the reverse rotation of the loading motor 7 by following a route completely opposite to the case of the loading operation described above. Regarding the above-mentioned loading mechanism, the applicant of the present invention filed Japanese Patent Application No. 59-20014.
Nos. 5 to 200153 are filed, and detailed description of the configuration and operation thereof will not be given here.

Various detection switches are provided in the housing 1. First, a disc detection switch 11 for detecting that the disc 3 is in the slot position is provided. The disc detection switch 11 is turned on when the disc 3 is set to the throttle position, and the disc 3 is removed from the position. When turned off, it turns off. The loading completion detection switch 12 is turned on by engaging the tray 6 after the disk 3 is placed on the turntable 10, and detects that the loading operation is completed. The eject completion detection switch 13 is turned on by engaging with the tray 6 that has reached the frontmost position (on the side of the front panel 2) during the eject operation of the loading mechanism, and detects that the eject operation is completed.

The disk 3 placed on the turntable 10 is rotationally driven by the spindle motor 9, and the recorded information is read by the optical pickup 14. The pickup 14 is mounted on a carriage (not shown) provided so as to be movable in the radial direction of the disk 3, and the carriage is driven by a carriage motor 15 via a gear mechanism 16. Each signal emitted from the operation key group 5 arranged on the front panel 2 and the above-mentioned respective detection switches 11 to 13 is transmitted to the control system shown in FIG. It

FIG. 3 shows the configuration of a control system. The control system is a microcomputer including a CPU (central processing unit) 20 which is the center of control and a RAM (random access memory) 21 as a storage means. It is composed. CPU20
Is a spindle servo circuit 22 for controlling the rotation speed of the spindle motor 9 and a carriage for controlling the rotation speed of the carriage motor 15 on the basis of the respective signals issued from the operation key group 5 and the respective detection switches 11 to 13. Servo circuit 23
And a motor drive circuit 30 for driving the loading motor 7
For example, a control signal is generated at a timing described later, and display data is output to the display 24 that performs various displays.

The read information read from the disk 3 by the pickup 14 is supplied to the CPU 20 after being subjected to signal processing such as demodulation and error correction in the signal processing circuit 25, and is also supplied to the D / A (digital / analog) converter 26. Converted to analog information,
It is output as an audio signal of the left (L) and right (R) channels via the electronic volume circuit 27. Further, a focus servo circuit 28 for controlling the position of the focal point of the information reading spot emitted from the pickup 14 and converged on the recording surface of the disk 3 in the direction perpendicular to the recording surface, and the above information for the recording track of the disk 3. A tracking servo circuit 29 for controlling the position of the reading spot in the radial direction of the disk is provided.

The focus servo circuit 28 controls to perform the focusing operation of the pickup 14 in response to a command issued from the CPU 20 when the reproduction is started or when the focus is defocused during the reproduction. The focus actuator (not shown) built in the pickup 14 is driven and controlled based on the focus error signal generated by a known detection method such as the method, and when the lock-in is performed when the focus servo is retracted, the lock-in signal is sent to the CPU 20. To send. On the other hand, the tracking servo circuit 29
A drive signal is supplied to a tracking actuator (not shown) built in the pickup 14 in response to a command issued from the CPU 20 during a jump or the like, and is generated by a known detection method such as a three-beam method during normal reproduction. By supplying the tracking error signal, the position of the information reading point in the radial direction of the disk is controlled.
The tracking error signal is sent to the cudge servo circuit 23.
Is also supplied to the carriage motor 15, and the low-frequency component becomes a drive signal for the carriage motor 15 during normal reproduction.

Since this disc player is mounted on a vehicle, the CPU 20 is operated by a backup power source, and each mechanism is operated by a main power source supplied by turning on a so-called accessory switch (not shown) of the vehicle.
However, among the respective mechanisms, only the loading mechanism including the loading motor 7 and its drive circuit 30 is operated by the backup power source so that the disk 3 taken into the housing 1 can be ejected even when the main power source is turned off. It is supposed to do. An Acc detection circuit 31 for detecting the disconnection of the main power supply is provided, and this Acc detection circuit 31 supplies a detection signal to the CPU 20 when the main power supply is disconnected.

As shown in FIG. 4, each of the keys in the operation key group 5 has a volume “UP” key 50, a volume “DOWN” key 51, and left and right channel commands for increasing (UP) and decreasing (DOWN) volume. A balance “L” key 52 and a balance “R” key 53 for balancing the volume are included. The processing when these keys are operated is performed by the CPU 20 as software. That is, when the volume “UP” key 50 or the volume “DOWN” key 51 is operated, the CPU 20 sends data and clock to the electronic volume circuit 27 so as to simultaneously increase or decrease the volume of both left and right channels. When the balance "L" key 52 or the balance "R" key 53 is operated, the data and clock are sent to increase the volume of one channel and decrease the volume of the other channel. Such a processing method will be described later. The change state of the volume at this time is displayed on the display 24. The quantum volume circuit 27 includes, for example, a plurality of resistors connected in series with each other and a plurality of analog switches connected in parallel to each of these resistors, and the plurality of analog switches are set in accordance with data from the CPU 20. A well-known structure that controls the volume by turning it on and off can be used.

Volume “UP” key 50 and Volume “DOWN” key 51
Each has a function of issuing a command to increase and decrease the volume as described above, and also has a function of issuing a command to reduce the volume at a time by, for example, about 20 dB when both keys 50 and 51 are operated twice. I carry it.

Next, the operation procedure of the present auto-loading disc player executed by the CPU 20 will be briefly described in the order of reproduction with reference to the flowcharts of FIGS. 6 to 12.

First, a series of operations of loading, playing, and ejecting will be described with reference to the flowchart of FIG. 6. The disk 3 is inserted into the housing 1 from the slot 4, and the second
When set to the slot position on the tray 6 as shown in the figure, the disc detection switch is turned on. CPU20
Detects that the disk detection switch 11 is turned on (step 1), it issues a loading command to the loading motor 7 via the motor drive circuit 30. As a result, the loading motor 7 rotates and the loading mechanism is activated to start the loading operation (step 2). The tray 6 carrying the disk 3 moves to the right from the position shown by the solid line in FIG. When it reaches above the turntable 10, it descends from that position to a position right below, so that the disk 3 is placed on the turntable 10 as shown by the chain double-dashed line in FIG. Is completed. At this time, the loading completion detection switch 12 is turned on. When the CPU 20 detects the loading completion by the ON output of the loading completion detection switch 12 (step 3), it shifts to the focus mode for focusing the pickup 14 (focusing) (step 4). This focus mode will be described later.

When the focus is taken in the focus mode, the reading operation of the pickup 14 is started. Prior to the reading of the program area, the reading of recorded information in the lead-in area of the disc 3 is started (step 5). After the rear display mode (step 6), the mode shifts to the play mode (step 7). The read TOC information is stored in the RAM 21. In the lead-in area of the disc, the number of songs recorded on the disc, the total absolute time,
The so-called TOC (Table Of Content
s) Information is recorded, and this TOC must be
You need to read the information. In the play mode, operations such as program selection, scanning and searching are performed in addition to normal sequential performance.

When the carriage (not shown) on which the pickup 14 is mounted reaches the movement limit position after the performance is finished and the detection switch (not shown) is turned on, the CPU 20 at this point detects that the performance is finished (step 8). , And issues an eject command to the loading motor 7 via the motor drive circuit 30. As a result, the loading motor 7 rotates in the direction opposite to that during the loading operation and starts the ejecting operation (step 9). In this ejecting operation, the tray 6 carries out a completely reverse process to that of the loading operation described above to carry out the disk 3 from the reproducing position to the slot position, and the tray 6 reaches the foremost position shown by the solid line in FIG.
When the eject operation is completed, the eject completion detection switch 13 is turned on.

When the CPU 20 detects the ejection completion by the ON output of the ejection completion detection switch 13 (step 10),
Then, it is judged whether or not there is a reload command due to a key input or the like in the operation key group 5 (step 11), and if there is a reload command, the loading command is again issued to the loading motor 7 via the motor drive circuit 30. To start the loading operation (step 12). When the completion of the loading operation is detected (step 13), the CPU 20
It is the same performance of the disc as last time, and its TOC information is RAM
Since it is stored in 21 and is valid, control is performed to immediately shift to the play mode (step 7) without reading the TOC information.

If it is determined in step 11 that there is no reload command after the ejection is completed, then it is determined whether or not the disk 3 has been removed from the slot position (step 14). The removal of the disk 3 can be detected by the off output of the disk detection switch 11. When it is determined in step 14 that the disk 3 has been removed from the slot position, the TOC information stored in the RAM 21 is invalidated (step 15) and an invalidation flag is set. With the above, a series of operations of loading, playing and ejecting is completed.

In the series of operations described above, the TOC information stored in the RAM 21 is not invalidated when the eject operation of the disk 3 is completed, but is invalidated only when the disk 3 is removed from the slot position. Therefore, if you continue playing the ejected disc,
There is no need to read the information again, and it is possible to move smoothly to the performance operation.

Next, the focus mode in FIG. 6 (step 4)
Will be described with reference to the flowchart of FIG.

The CPU 20 first issues a focusing operation start command to the focus servo circuit 28 (step 20), and at the same time, starts a timer for a fixed time Ta built in the CPU 20 (step 21). Then, it is determined whether or not the focus servo is locked in (step 22), and if locked in, the timer is cleared (step 23), and then the process returns to the main flow of FIG. Note that it is possible to determine whether or not the focus servo is locked in by using the lock-in signal generated from the focus servo circuit 28 when the focus servo is locked in.

When it is determined that the lock-in is not performed in step 22, it is determined whether or not Ta has passed for a certain time (step 2
4) If the time has elapsed, an eject command is issued to the loading motor 7 via the motor drive circuit 30 in order to eject the disc loaded at the reproduction position (step 25). That is, if the disc cannot be focused due to scratches or stains on the disc, or the disc is turned upside down, the disc is ejected after a certain time Ta has elapsed.

After the eject command, it is judged whether or not there is a reload command due to key input or the like in the operation key group 5 (step 2
6) If there is no reload command, the ejection completion is detected (step 27), and the operation is stopped thereafter. If it is determined in step 26 that there is a reload command, the key input for the command is ignored (step 28), and then the process proceeds to step 27.

In other words, when the disc is ejected while the disc is out of focus due to scratches or stains on the disc, or when the disc is turned upside down, etc., the disc reload command is not accepted and the eject operation is switched to the loading operation. It is prohibited. As a result, when the disc is inserted upside down, the user can immediately judge it, and when the disc is scratched or dirty, it is possible to prevent the disc from playing.

Next, the display mode (step 6) in FIG. 6 will be described with reference to the flowchart in FIG.

In the main flow of FIG. 6, the TOC information reading is started (step 5), and then the main display mode is entered.
In addition, a predetermined information is displayed, for example, by using one segment at the center of a 7-segment display as shown in FIG.
When the TOC information is completely read (step 31), the timer for a certain time Tb (for example, 5 seconds) built into the CPU 20 is started (step 32) and read at the same time. The TOC information, that is, the number of pieces of music and the total absolute time are displayed (step 33). Note that in the flowchart of FIG. 6, the display mode and the play mode are shown as different modes for convenience of description, but it is assumed that the play operation is started after the TOC information is read in the display mode.

Normally, at the time of so-called setup after reading the TOC information after the loading of the disc and shifting to the play operation, the TOC information is not yet read, there is no data that can be displayed on the display 24, and nothing can be displayed, so the user In some cases, it may not be possible to determine what kind of operating state the player is in. However, as described above, it is possible to notify the user that the player is in the set-up state by displaying something even if there is no TOC information. The display information in this case is
The display is not limited to the blinking display of "---" using a 7-segment display.

When it is detected that another mode is designated by key input of track ±, FF, REV, etc. on the operation key group 5 while displaying the number of songs and total absolute time, etc. (step 34), The timer is cleared (step 35), and at the same time, the performance (playback) status information, that is, the song number (track number), based on the read information of the pickup 14 that is playing the program area, the elapsed time from the start of the performance of each song ( minute second)
Is displayed (step 36). These performance status information is the Q of the subcode signal in the so-called CD format.
It is recorded in the channel and can be detected from the read information of the pickup 14. Further, in the state where the number of songs and the total absolute time etc. are displayed, if there is no other mode designation and it is determined that the display state has passed for a certain time Tb (step 37), the process proceeds to step 36 and Switches to the display of performance status information.

That is, the read TOC information is displayed for a fixed time Tb, and if another mode is designated before the elapse of the fixed time Tb, the performance status information is displayed at that time.
After a certain time Tb has elapsed, the display automatically switches to the performance status information display.

Next, the operation when the focus is lost during play will be described with reference to the flowchart of FIG.

The CPU 20 constantly monitors the lock-in signal generated in the lock-in state with the servo loop from the focus servo circuit 28 in a predetermined cycle, and when it detects that the lock-in signal disappears, it determines that the focus is out of focus, and the focus servo A focusing operation start command is issued to the circuit 28 (step 40), and at the same time, a fixed time T
The timer of c is started (step 41). And
It is determined whether or not there is a disc eject command or a stop command by key input in the operation key group 24 (step 42), and if not, it is determined whether or not the focus servo is locked in (step 43). When the focus servo is locked in, that is, when the focus is taken,
The timer is cleared (step 44), and then the play operation is started again. When the lock-in signal of the focus servo is not obtained within the fixed time Tc (step 45), it is determined that the focusing operation could not be achieved (focus NG) at this time, and the NG counter built in the CPU 20 is incremented ( Step 46). And
It is judged whether or not the count value N of this counter reaches a predetermined value, for example, "16" (step 47). If N ≠ 16, the process returns to step 40 and the focusing operation is performed again until focus is achieved. Focusing operation is repeated up to 16 times continuously.

If the focus cannot be obtained even after repeating the focusing operation 16 times in succession, the NG counter is cleared (step 48), and then the stop state is set (step 4).
9). Here, the stop state means a state in which the disc is at the reproducing position and the main power supply is cut off to stop the operation of each mechanical unit. In this stop state, when it is detected that a play command is issued by a key input in the operation key group 5 (step 50), the process proceeds to step 40 and the focusing operation is started again.

In this way, by limiting the number of times the focusing operation is repeated continuously, it is possible to reduce the load on the servo system including the focus actuator and to prevent the pickup 14 from generating heat.

If there is a disc eject command or a stop command during the focusing operation (step 42), the process moves to step 48 to clear the NG counter, and then the stop state is set. When there is a disc eject command, the disc eject operation is performed after the stop state. In this way, by clearing the NG counter when there is an eject command or a stop command, even when performing the focusing operation again after shifting from the stop state to the play state, focusing can be performed up to 16 times in succession. The operation can be repeated.

Next, as a special operation, an operation when the accessory switch of the automobile is turned off at the time of playing will be described with reference to the flowchart of FIG.

The CPU 20 constantly monitors the detection output of the Acc detection circuit 31 in a predetermined cycle, and the main output (Acc) is detected by the detection output.
When the disconnection of the key is detected (step 60), the operation key group 5 continues.
It is determined whether or not there is an eject command by the key input at (step 61), and if there is an eject command, the loading motor 7 is instructed to the loading motor 7 via the motor drive circuit 30 in order to eject the disc at the reproduction position. Issues an eject command (step 62). After the eject command, it is judged whether or not there is a reload command due to a key input or the like in the operation key group 5 (step 63). If there is no reload command, the eject completion is detected (step 64), and the operation thereafter. It will be stopped. If it is determined in step 63 that there is a reload command, the key input for that command is ignored (step 65), and then the process proceeds to step 64.

That is, while ejecting the disk due to the disconnection of the main power supply, the disk reload command is not accepted,
The transition from the eject operation to the loading operation is prohibited. This makes it possible to prevent the battery voltage from decreasing without repeating the loading operation and the ejecting operation.

Next, in the operation key group 5, the volume “UP”, “DO
A key processing method executed by the CPU 20 when the "WN" key 50, 51 and the balance "L", "R" keys 52, 53 are operated will be described.

First, in the case of the volume “UP” and “DOWN” keys 50 and 51, these keys have the function of instructing the volume increase and decrease, respectively, and both keys operate ( It also has a function of issuing a command to lower the volume by about 20 dB at a time when the key is pressed (so-called double press). The key processing method will be described below with reference to the flowchart of FIG.

The CPU 20 constantly monitors whether or not any one of the operation key groups 5 is pressed in a predetermined cycle (step 7
0), if any key is pressed, it is determined whether or not the key is the same key as in the previous cycle (step 71). If the key is different from the last time, CP
The chattering counter built in the U20 is started (step 72), the double press timer built in the CPU 20 is cleared (step 73), and the double press check flag is turned off (step 74). The chattering counter is a counter for absorbing chattering during key operation to prevent malfunction, the double-press timer is a timer for monitoring double-press of the key, and the double-press check flag is for the operated key. This is a flag indicating that the key is for double pressing.

If it is determined in step 71 that the key is the same as the previous key, it is determined whether the chattering counter has counted over (step 75). If it is over, it is determined whether the double check flag is on. Is determined (step 76). In the previous cycle, since the double press check flag is turned off in step 74, it is then determined whether or not the pressed key is the double press key (step 77). If the key is a key for use, the double press timer is started (step 78), and the double press check flag is turned on (step 79).

As described above, when one of the two double-pressing keys is pressed, the double-pressing timer is started, and during the operation period of the timer, the key is not pressed, that is, the key is released. If it is determined that the double press check flag is turned on (step
80) and then validate the key (step 81).

Similarly, during the operation period of the double press timer, it is judged whether or not the timer is over the time through step 76 (step 82). In the case of time over, the key pressed at that time is regarded as valid. Yes (step 81). If the time is not over, it is determined whether or not the key is double-pressed (step 83). If the key is double-pressed, the process proceeds to step 81 and both keys are validated and the key is doubled. Accept push.

That is, the CPU 20 activates the double-press timer when the double-press key is pressed, and one of the two double-press keys is pressed during the timer operation period. When the key is released, the key is accepted, and when both keys are pressed, it is accepted as a double press. When the timer operation period expires, one of the two keys is pressed. If so, the process for accepting the key is performed. After accepting each key, data and clock are sent to the electronic volume 27 (see FIG. 4) to execute the function of each key or the double-press function.

Thus, by providing the double-press timer and detecting that one key is pressed and then released during the operation period of the timer, one key process can be performed even during the timer operation period. , It will be possible to quickly respond to quick repeated key operations.

In this embodiment, as the key processing method for the double-push key, the volume "UP" and "DOWN" keys 50 and 51 have been described, but the key processing method is not limited to these keys. Further, the applied device is not limited to this disc player.

Next, a processing method in the case of adjusting the balance of the volume of the left and right channels by the balance "L" and "R" keys 52 and 53 will be described with reference to the flowchart of FIG.

The CPU 20 constantly monitors whether or not any one of the operation key groups 5 is pressed in a predetermined cycle, and when pressed, the key is the balance "L" or "R" key 52 or
It is determined whether it is 53 (step 90). When any key is pressed, the key identification data corresponding to that key is stored in the register built in the CPU 20. If neither of the balance "L" and "R" keys 52, 53 is present, the register is reset (step 91), and then the next cycle is awaited.

If it is determined in step 90 that the balance "L" or "R" key 52 or 53 is pressed, the key identification data stored in the previous register and the key identification data of this time are compared to determine that It is determined whether or not the key is the same as the key used in the previous cycle (step 92). By this determination, it can be determined whether or not the same key is continuously pressed. If the key is not continuously pressed, the key identification data in the register is rewritten (step 93), and then it is determined whether or not the key is the balance "L" key 52 (step 94). When the balance "L" key 52 is pressed, data and clock are sent to the electronic volume 27 (see FIG. 4) in order to increase the volume of the L channel and decrease the volume of the R channel (step 95). If the balance "R" key 53 is pressed, the opposite control is performed (step 96).

If it is determined that the buttons have been pressed continuously in step 92, the left and right channels are balanced in volume (center balance state).
It is determined whether or not (step 97), and if the balance is not achieved, the process proceeds to step 94 to perform the same operation as described above, and if the balance is achieved, the acceptance of continuous pressing is stopped at that point. The center balance state can be detected by comparing the data of the left and right channels sent to the electronic volume circuit 27 and observing the coincidence of both data.

In this way, if the balance key is in the center balance state while it is continuously pressed, the so-called center click effect can be obtained by stopping acceptance of continuous press at that point, so the center balance state can be easily and reliably obtained. In addition to being able to obtain, it is possible to operate without looking at the display. Therefore, it is particularly useful for in-vehicle devices that are often operated without checking the display.

In the present embodiment, the case where the above-described volume balance processing method is applied to the electronic volume circuit in the disc player has been described, but the present invention is not limited to this, and a normal tone control circuit, fader control circuit, or the like can be used. Is also applicable.

Effects of the Invention As described above, according to the display method of the present invention,
Reading from the lead-in area is performed by displaying the read information for a predetermined time after reading the recorded information in the lead-in area and then displaying the reproduction status information based on the read information in the program area. Since a switch for switching the display between the information and the information read from the program area can be omitted, it is possible to contribute to the effective use of the operation panel surface.

Also, if another mode is designated within the above-mentioned predetermined time, by immediately shifting to the display of the reproduction status information,
It is also possible to improve the usability of the player because it is possible to immediately understand how the operation of the player has changed.
